Hi all,
I am using rgdal to read ArcInfo binary grids produced by ArcGIS. The latest public version of rgdal, which binds with GDAL 1.6.1, fails with the error message in the subject line of this email. I reported this a couple of weeks ago in http://lists.osgeo.org/pipermail/gdal-dev/2009-July/021369.html. Today, the rgdal developer (Roger Bivand) provided me with an rgdal built against the 1.6.2 release candidate issued 31 July. The problem still exists. The problem had apparently been seen before. My original email prompted a review of the issue, including mention of it being tracked in tickets #2447 and #3031. Evan made some checkins on 22 July that I thought would result in this being fixed in both the trunk and the next release of 1.6 (which would be 1.6.2). But I guess I did not fully understand it, and I missed the fact that neither of these issues appeared in Howard's 31 July release candidate email. So: is there any chance the GDAL team can fix this in either 1.6.2 or, if it is now too late, 1.6.3? It may be that this fell off the radar because the severity of the tickets (for example, #3031 is minor), or because there was a suggested workaround that users could simply rename the "info" directory to prevent GDAL from failing. Well the issue is indeed severe if you are an ArcGIS user. In my case, the rasters were produced by ArcGIS 9.3.1. Presumably ESRI is generating the rasters correctly. The workaround of renaming the info directory is not a good idea. That renders all of the rasters in a directory inaccessible to ArcGIS. It is a major corruption of the ArcInfo binary grid format to do so. I'm not sure why it was suggested in the first place, but it is a very bad idea. I'm sorry for not staying on top of this issue and somehow missing that it was not put into 1.6.2 and that the workaround is such as bad idea. In any case, could you please consider fixing this in 1.6 soon? I can provide example data if needed. Thanks, Jason
